This paper seeks to extend the analysis of performance management regimes by Bouckaert and Halligan to other countries in order to contribute to the developing theory of forms and challenges in public sector performance management.

The state of performance management and the context in which it has evolved is assessed in seven different countries using dimensions drawn from Bouckaert and Halligan's work along with elements from earlier work by Pollitt and Bouckaert. These are summarized in a table and comparisons made to generate additional insights into the factors that influence the shape and speed of public management evolution.

The paper finds that the Bouckaert and Halligan framework for analyzing public sector performance management is useful, albeit with some modifications. Specifically, it finds that administrative culture is a key factor influencing the speed of reform and that the attitude of elites (politicians and civil servants, in most cases) is also a vital piece of the puzzle that was not included in Bouckaert and Halligan, but did appear in the earlier framework of Pollitt and Bouckaert. It also finds evidence that economic and political crises occurring together accelerate the introduction of integrated performance management systems, but that trust in government does not appear to be a significant factor. Finally, the paper observes that, absent political crisis/commitment, governments will prioritise “external” performance measures such as customer service, participation and transparency objectives over “internal” performance measures such as financial, staff management and whole of government reporting.

The countries studied provide a rare insight into lesser‐known performance management regimes and the use of the Bouckaert and Halligan framework allows for comparisons to earlier (and future) research. The findings will be of interest to scholars in public administration reform and performance management.

This paper sets out to corroborate the existing literature on investors' risk tolerance and to assess how the 2008 financial crisis has affected risk tolerance among Italian investors.

Based on a unique dataset of real-world portfolio choices made by 1,245 Italian investors over a period of 15 years (from 2003 to 2017), this paper presents two steps of analysis. In step 1, the whole period 2003–2017 is considered with the aim to integrate and corroborate the existing literature on the topic of risk tolerance, considering a complete economic and financial cycle. Step 2 took 2008 as the pivotal point between pre-crisis (2003–2008) and crisis (2009–2017) with the aim to observe the influence on risk appetite of the economic and financial effects of the crisis.

The results obtained confirm that men are more risk tolerant than women and older people are less risk-taking than their younger counterparts, although the relationship between age and risk tolerance is not necessarily linear. Moreover, our paper demonstrates that a crisis scenario has an influence on Italian investors' risk tolerance.

Our results are of interest to financial advisors, financial planners, asset managers, psychologists, behavioral researchers and more in general to providers of financial products and services.

The results presented in this paper are relevant and original because they are based on real investors who made real choices concerning their portfolio asset allocations.

This paper aims at supporting business process designers in modelling collaborative scenarios in terms of hierarchical BPMN collaboration diagrams, to enforce consistency among different hierarchical levels.

The proposed approach is based on a set of guidelines to apply during the modelling of hierarchical diagrams. These guidelines address consistency issues related to the hiding capability provided by sub-process and call activity elements, which may obscure behaviours at inner levels, especially exchange of messages, that are inconsistent with those in other hierarchical levels. A laboratory experience validates the guidelines' effectiveness.

The paper points out the issues of hierarchical diagrams, and the lack of support in this context from the existing BPMN modelling tools. Moreover, through a laboratory experience, the paper shows the benefits carried by the proposed guidelines concerning the quality of the modelled diagrams.

The proposed guidelines have been implemented in a consistency checking tool that avoids consistency errors during the modelling activity. To foster its usage, the tool has been integrated into the Eclipse BPMN modelling environment.

The paper, employing consistency guidelines, provides a novel solution to the weaknesses of hierarchical modelling.

This paper investigates the stock market reaction to three different events related to the UEFA Champions League – the announcements of draws, odds and match results. The aim of the paper is to test whether these events are informative for stock market operators, i.e. whether they produce abnormal returns.

Applying the event study methodology, the authors investigate the stock market reaction before (at two events: the draw date and on the release of betting odds) and after the matches of 11 listed soccer teams in the period 2003–2019. The authors also conduct OLS regression analyses in order to disentangle the impact of firm specific variables and match characteristics on cumulative abnormal returns.

This paper finds that match outcomes affect the stock market performance of listed teams, while the announcements of draws and odds do not. More specifically, the market does not consider match outcomes involving wins and ties as informative events, while it penalizes losing teams. Moreover, investor reactions to events related to the UCL competition depend more on match characteristics than on company specific variables.

The study enriches the ongoing debate about the impact of soccer team results on stock market performance in several ways: using the widest time span ever adopted in this area; focusing on UCL, which is the most important soccer competition played by private clubs; disentangling for the first time the effects of draws, odds release and sporting outcome on stock returns of listed soccer clubs.

In the redesign process of assembly components that need adaptation to robotic assembly, designers can find support from structured methodologies for innovation, such as the theory of inventive problem solving (TRIZ). This paper aims to illustrate the authors’ methodology for redesigning gas hobs components for adaptation to robotic assembly.

A designer approaching a redesign task of an assembly component of any kind for adaptation to robotic assembly must consider, first of all, the features and limitations of existing robotic assembly systems; the generation of new design ideas that best fit the requirements may result to be a very challenging task. Here, the TRIZ methodology has proven useful for generating design ideas and finding the best solution.

The authors’ methodology approaches the challenges of redesign tasks for robotic assembly adaptation, which exploits knowledge of automatic and robotic assembly systems and the TRIZ method for innovation; it has proven useful in the redesign, checks and prototyping of gas hobs components.

This paper shows how the TRIZ methodology can be integrated into the redesign process and its impact on an industrial environment. The work’s main value is to provide a set of steps to help the designers change their design components approach that is necessary but not still implemented to optimize the use of the automation.

The purpose of this paper is to provide a flexible and extensible model for the classification of suppliers, within the purchasing guidelines and market trends of an Italian small company, leader in the production of street lamps. The model is applied to identify critical supply chains with the final objective of lead-time reduction.

The model is obtained by the application of the purchasing portfolio analysis through the construction of Kraljic matrix. Profit impact and supply risk criteria are selected according to the main company requirements, and then prioritized by the analytical hierarchy process (AHP). Finally, supply chain lead-times are analyzed with Gantt diagrams.

The application of the model allows the determination of company criticalities in terms of high lead-times and of the involved suppliers. The analysis of critical suppliers positioning in the Kraljic matrix allows the definition of some possible strategies to implement for lead-time reduction.

Purchasing portfolio analysis and Kraljic matrix are practical instruments to quickly frame company purchasing situation, but their application is not simple due to the numerous and different factors involved, especially in small and medium enterprises (SMEs), where resource are scarce and several constraints limit operations. The objective of the research is the development of a practical tool for strategic purchasing, simple and robust to be implemented in SMEs, with limited resources and access to quantitative supplier data.

Evaluation criteria definition is one of the most difficult phases, such as their univocal and quantitative comparison. The problem of selecting and prioritizing both quantitative and qualitative criteria for suppliers classification is overcome with the combined application of Kraljic matrix and AHP. The newly integration of the two methodologies allows the realization of a reliable and robust model for suppliers classification, which can be easily adapted to company business strategy changes.

The purpose of this paper is to investigate consumers' reactions to a new kind of green food product that is the so-called lab-grown meat (LGM). This kind of meat does not derive from animal or vegetal cultures but is produced on the basis of “tissue-engineering” technologies, by injecting muscle tissue from an animal into a cell culture, allowing cells to “grow” outside the animal's body. By considering the similar nutritional characteristics of traditional types of meat, and the potential in terms of sustainability, the authors investigate the effect of the advertising, communication focus promoting LGM-based meat, on consumers' willingness to buy (WTB) and word-of-mouth (WOM), by shedding light on the moderator role of consumers' environmentalism and status consumption orientation tendency in influencing such relationship.

Through an exploratory research design, the authors conducted a study based on a two-cell experiment that manipulated the advertising communication focus by using a hamburger made of synthetic meat related to a fictitious brand called “Gnam”, to manipulate the advertising communication focus (sustainability vs. taste), then evaluating consumers' WTB, WOM, environmentalism and status consumption orientation.

Results show that the communication focus (sustainability vs. taste) exerts a positive effect on consumers' WTB and WOM, and how such effect is magnified both by consumers' environmentalism and status consumption orientation, in the attempt to show other a green status and their green consumption tendency.

Despite the promising results, the study does not consider other consumers' individual differences, i.e. as for the role of age, or cultural differences.

Practically, this study suggests marketers and managers how to design effective marketing campaigns to incentivise LGM-based food products purchase, and promote positive WOM, on the basis of certain consumers' individual differences useful to segment their clientele in terms of environmentalism, and status consumption orientation tendency.

Socially, this study may contribute to incentivising the use of alternative forms of meat as a food product not deriving from animal or vegetal culture, coherently with recent sustainability worldwide claimed goals.

This is the first paper to investigate consumers' reactions to LGM-based food products, by shedding light on the fundamental role of consumers' individual differences.

Ubiquitous web applications (UWA) are a new type of web applications which are accessed in various contexts, i.e. through different devices, by users with various interests, at anytime from anyplace around the globe. For such full‐fledged, complex software systems, a methodologically sound engineering approach in terms of model‐driven engineering (MDE) is crucial. Several modeling approaches have already been proposed that capture the ubiquitous nature of web applications, each of them having different origins, pursuing different goals and providing a pantheon of concepts. This paper aims to give an in‐depth comparison of seven modeling approaches supporting the development of UWAs.

This methodology is conducted by applying a detailed set of evaluation criteria and by demonstrating its applicability on basis of an exemplary tourism web application. In particular, five commonly found ubiquitous scenarios are investigated, thus providing initial insight into the modeling concepts of each approach as well as to facilitate their comparability.

The results gained indicate that many modeling approaches lack a proper MDE foundation in terms of meta‐models and tool support. The proposed modeling mechanisms for ubiquity are often limited, since they neither cover all relevant context factors in an explicit, self‐contained, and extensible way, nor allow for a wide spectrum of extensible adaptation operations. The provided modeling concepts frequently do not allow dealing with all different parts of a web application in terms of its content, hypertext, and presentation levels as well as their structural and behavioral features. Finally, current modeling approaches do not reflect the crosscutting nature of ubiquity but rather intermingle context and adaptation issues with the core parts of a web application, thus hampering maintainability and extensibility.

Different from other surveys in the area of modeling web applications, this paper specifically considers modeling concepts for their ubiquitous nature, together with an investigation of available support for MDD in a comprehensive way, using a well‐defined as well as fine‐grained catalogue of more than 30 evaluation criteria.
